FILM PROTECTOR.

Application filed Sveutember 12, 1921. Serial No. 500,092.

To all whom it may concern:

Be it known that we, HARRY T. BROWNE and FRANoIs L. Diano, citizens ofthe United States, residing at Mobile, in the county of Mobile and State.of Alabama, have invented certain new and useful Improvements in FilmProtectors; and we do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to an improved protector and one object of theinvention is to provide a protector lwhich may be applied to the edgeportion of a. strip of moving picture film and will serve to strengthenthe film and prevent its being torn while being passed through aprojectingl machine or while being rewound. It very often happens that afilm will be broken while being used or rewound and this causes damageto the film.

Another object of the invention is to provide a protector having aconstruction which will permit of its being used as a binding for theside edge portions of the strip of film and to further provide a veryefficient means for connecting adjoining ends of strips of binding. l

Another object of the invention is to provide a reinforcing binding forthe strip of film which is so constructed that it will not materiallyadd to the thickness of the film and will therefore permit it to passeasily through the projecting machine.

This invention is illustrated in the accompanying drawings, wherein:

Figure 1 is a plan view showing the reinforcing and protecting stripplaced fiat.

Figure 2 is a plain view showing the reinforcing strip applied to astrip of film.

Figure 3 is a longitudinal sectional view taken along the line 3 3 ofFig. 2.

Figure 4 is a transverse sectional view taken along the line 4--4 ofFig. 2.

This improved reinforcing means is for use in connection with a strip ofmoving picture film 1 and will be in the form of binding to be appliedto the side'edge portions of the strip of film.' The binding' will beformed of very light metal or any other suitable material. This bindingwhich is indicated in general by the numeral 2 is to be foldedlongitudinally upon the dotted lines 3 thus providing sections 4 and 5for extending upon opposite faces of the strip of film 1 as shown inFig. 4 and as shown in Fig. 3. It should also be noted that this binderstrip has its side portions provided with openings 6 and 7 and that theportions of the strip about the openings 7 are struck in to provideflanges 8 which will extend through the openings usually formed in theside port-ions of the film 1. The teeth of the feeding wheel `of aprojecting machine can thus engage the film in the usual manner toproperly feed the film through the projecting machine. The outer sideportion of the binder strip 2 is elongated to provide the tongueextension 9 which terminates in a fastener .tongue 10 which is similarto the fastener tongue l1 provided at the end of the inner portion ofthis binder strip. At the opposite end, the

binder strip has its inner side portion provided with a tongue extension12 which is of a length equal to that of the tongue extension 9 and thistongue extension and the end of the other side portion will beperforated as shown at 13 and 14 thus-providing slots to receive thefastener tongues l0fand 1l. It will. therefore be seen that if it isfound that it is necessary to use more than on length of binder in orderto bind an entire strip of film, the adjoining end portions of the twostrips of binder may be spliced with the tongue extensions 9 andl 12extending in overlapping relation and the tongues 10 and 11 extendingthrough the slots 13 and 14 and bent over to a clamping position asshown in" Figs. 2 and 3.

This binder strip may be su lied either flat or in a folded condition.Vgiien applied to a strip of film, the binder strip is to be applied toeach side of the strip of film with the openings of the film registeringwith the openings in the inner side portion 5 and the fianges 8extending through `the openings in the film. When it is necessary to addadditional binding strips as would be the case where the binding stripsare not of the same length as the strip of film, the two sections ofbinding strip will be connected as previously explained. It will thus beseen that there has been rovided a de- -vice for binding and stren eninga strip of moving picture film wlnch will serve to prevent the film frombeing broken While being fedvthrough the projecting machine or whilebeing rewound upon a drum.

We claim: A

1;-The combination with a strip of-moving picture film having sideopenings. for receiving prongs of a feeding Wheel, of binding strips.for the side portions of the film doubled longitudinally for extendingupon opposite faces ofthe film and having the portions overlapping thefilm pro-vided With openings registering with the openings in the film,the portion of the binding stripi extending acrossone face of thepicture film provided with struck-in portions forming flanges about itsopenings, said flanges extending through the registering openings of thefilm and engaging the portion of the binding fitting against the secondface. of the film.

` 2. A'binding 'of the character described comprising a strip foldablelongitudinally to provide side portions having openings formed therein.to register when the strip is folded, one side portion being extendedbe- Mimet yond the second side portion at one end and terminating in apenetrating prong, the

.binding at the opposite end having the the extended ends of connectedbinder strips may be ositioned inoverlapping relation and the fastenerprongs passed through the slots and bent to a locking position.

3. A binder strip. for a strip of moving picture film, said binder stripbeing doubled longitudinally to provide side sections having openingsfor registering with side openings formed in a strip of picture film,one side portion being provided with flange extensions about itsopenings for extending through openings in a strip of picture film andengaging the second side portion of the binder strip.

lfn testimony whereof We have hereunto set our hands.
